Workaround for jstack -l

I've an java app named my-app which is running from specific user my-app-user and I want to take thread dumps once in a hour. I found jstack which is bundled with JDK and I want to execute it with -l flag. But, unfortunately I found that I should run jstack as my-app-user user if I want to get my thread dump. The problem is that jstack has root:root ownership and I can't change it. Are there some workaround for this problem? I have no idea how can I resolve this.

Thanks

Solution 
  • $ sudo -u my-app-user jstack -l
